Atotal of 725 tickets were sold for the school play. they were either adult tickets or student tickets. there were 75 more student tickets sold than adult tickets. how many adult tickets were sold?

X= number of student tickets soldx+75= number of adult tickets sold
Add the number of student and adult tickets together to total 725 tickets

x + (x + 75)= 725
combine like terms
2x + 75= 725subtract 75 from both sides
2x= 650divide both sides by 2
x= 325 adult tickets

x + 75= 400 student tickets

ANSWER: There were 325 adult tickets sold
Hope this helps!  :)

2b^2+9

when b=3

First we have to replace b by the number giving

2(3^2)+9

(2)(9)+9

18+9

= 27

I hope that's help !
